This paper presents the advantages of modelling an application destined for automotive using automotive standard architecture (AUTOSAR). This standard is structured in layers and is trying to make the software application independent from the microcontroller unit (MCU) specifications. By structuring an application in this way, it reduces the time and the cost of developing new ones for a different microcontroller or for creating new applications with a similar purpose for the same microcontroller. Also, the diagnosis for the errors is improved a lot, because it provides mechanisms to detect them, and, having a very structured form, it is easy to find them in comparison with the older procedures used for the soft-ware development that are different from one producer to another. This standard architecture helps to get better results in software development and embedded systems for the automotive area. Here is presented a primitive implementation for an electric automatic gearbox that can be developed more when new features are required. |
